FLUSHING APPARATUS.

SEECIFICATION forming part of Letters .Patent N o. 748,046, dated December 29, 1903.

Application led March 2, 1903.

To a/ZZ whom it mayr concern:

Be it known that I, JOHN H. BYERS, a citizen of the United States, residing at San Francisco,oounty of San Francisco, and State of California, have invented certain new and useful Improvements in Flushing Apparatus; and I hereby declare the following to be a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to iiushing devices for water-closets and like purposes and to y certain improvements therein, as hereinafter described, and illustrated by drawings forming a part of this specification.

My improvement consists in a vessel or receiver connected to a pressure water-service and adapted to hold a ushing charge of water, alsoaquantityofairentrapped therein; atthe bottom of this vessel a flushing orrdischarge valve operated by a rod or stem that passes downward into the flushing or discharge way, from the main valve. This main valve is connected to a float in the main vessel, which latter by its buoyancy holds the valve open when raised and by its gravity assists in closing the valve when the charge of water e'scapes down through the finishing-pipe.

It also consists in the manner of operating the dashing-valve, rendering it automatic, and in other features .hereinafter described in connection with the drawings.

rI"he objects of my invention are to provide a flushing device wholly inclosed, without adjustments, and secure from being tampered with, one that can be set above or below the receptacle to be flushed, discharging by the service-pressure without siphoning action by means of a valve operated from the flushing or discharge way below the main vessel; also avoids the use of a separate inlet or supply valve with its attendant mechanism; also has other objects hereinafter explained. To these ends I apply devices as illustrated in the drawings herewith.

Figure I is an elevation, mainly in section, showing the operating parts of a iiushing device made according to my invention; and Fig. II a transverse section on the line ot a in Fig. I.

The supply-tank 1 is made to hold the required quantity of water, exclusive of an air- Serial No. 145,715. (No model.)

space 2 above the dotted line c c, that varies with the pressure and is closed at the bottom by being attached to a base-plate 3 by screwbolts 4, as shown in Fig. I. In this baseplate 3 is inserted a valve-seat 5, closed by `the dashing-valve 7, opposite which is a nipple 8 to receive the liushing-pipe 9, and at `the back of this plate is an angular flange 10 for attaching the structure against a wall or vother support in the usual manner.

The valve 7 is rigidly attached to a rod or stem 12,that passes through a guiding-bracket 13, an'adjustable collar 14, and a lioat 15, fastened to the stem 12 by a screw 11. Above the oat is placed a yielding spring 17, the tension of which is regulated by a movable collar 18 for.I purposes hereinafter explained.

A supply-pipe 19 connects to the servicepipes or other source under water-pressure and is provided with a valve 20, by which the rate of flow or the time of filling the vessel 1 can be regulated. The inner end of this pipe 10 is arranged to discharge downward, as shown at 21.

A stein 16 extends from the valve 7 down through the ushing-pipe 9 to a chamber 22 and is there connected to an inclosed lever 23, attached to an oscillating shaft 24, on the outer end of which is fastened the operatinglever 25, moved by a chain 26 or push-rod in the usual manner.

The chamber 22 forms a section or part of the Frushing-pipe 9 and is provided with a gland 27 around the shaft 24, so the waterways ofthe whole structure are sealed against leaking water or gas.

In operating, service-.water under pressure is admitted to the vessel 1 through the valve 20 and pipe 19 at a rate that will charge the vessel in from two to ten minutes or accordingly as the frequency -of flushing. The Weight of the stem l2 and its connected parts, together with the pressure in thevessel l, holds the valve 7 shut against the buoyancy of the iioat 15 while the vessel 1 is filling. As the vessel 1 is filled through the pipe 19 the air therein is compressed by the'waterpressure into a space more or less in volume, accordingly as the service-pressure.

To operate the device, the lever 25 is depressed, raising the valve 7, so the water in the vessel 1 is forcibly discharged down the ICO oat 15 and valve 7 are so proportioned that the float will open the latter by itsbuoyancy, the han d-operating devices are detached, and the screw 1l is loosened so the float 15 will slide on the stem l2.

The spring 17 is so set that the float 15 will admit the required amount of water before opening the valve 7 and will then descend and close the valve, the operation `going on automatically at periods determined by the rate at which supply-water is admitted by the cock 20. In this manner it will be seen that the various devices when once set require no adjustment, can be placed at any convenient point above or below the receptacle or place to be flushed or on the same level; that the whole is in cased and no separate water-supply apparatus is required alsothat the force of the flushing-water is greatest at first and is graduated to meet the requirements.

Having thus explained the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is

In a flushing device, a main vessel or receiver, a discharge-valve therefor, a oat in the receiver connected to this valve by astem on which the float may slide and a spring above the float to regulateits range whereby an automatic intermittent discharge of flushing-water is obtained, in the manner and for the purposes specified.

In testimony whereof I have signed my name'to this specification in the presence of two subscribing witnesses.

JOHN H. BYERS.
